Let us first review the process (I). Fig. REF (a) depicts the propagation of quantized light through a scattering lens [1]}, [2]}, [3]}, [4]}, [5]}, which comprises randomly distributed small particles for light scattering. To characterize the scattering lens, two primary factors are introduced: the transport mean free path \(l\)  and the thickness \(L\) . If \(l \ll L\) , the multiple scattering events would occur and result in a speckle pattern [6]}. Hereafter we define \(s \equiv L/l\)  which determines the degree of disorder.
